The correct statements regarding the Coriolis effect's role on ocean currents are:
- The Coriolis effect turns currents counterclockwise in the Northern Hemisphere.
- The Coriolis effect turns currents clockwise in the Southern Hemisphere.
- The Coriolis effect turns wind to the right in the Northern Hemisphere.
- The Coriolis effect turns wind to the left in the Southern Hemisphere.
So, the most correct options related to the typical understanding are that the Coriolis effect turns currents counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere, as well as affecting wind movement.
